v APPARATUS FOR DRYING WARP, 84.0.

SPECIFICATION forming part of Letters Patent No. 454,913, dated. June30, 1891. Application filed January 4, 1888. Serial No. 259,758. (Nomodel.)

To all whom it neay concern:

Be it known that I, JOHN H. LORIMER, of the city and county ofPhiladelphia, and State of Pennsylvania, have invented an Improvement inApparatus for Drying WVarp, 850.,v of which the following is aspecification.

My invention has reference to drying-machines for textile strands, suchas warp; and it" consists in certain improvements, all of which arefullyset forth in the following specification, and sho wn in theaccompanying drawings, which form part thereof.

Heretofore it has been customary in drying warp to pass a chain orstrand composed of, say, one hundred warp-threads around hollowsteam-heated cylinders, such as are used in calico-drying, and relyingupon the evaporation which must take place by the contact of the wet ordamp warp with the solid surface of the hot cylinders. Such apparatus isvery expensive to make, takes up a large amount of room, dries slowly,andis costly in operation.

My object is to produce a machine capable of overcoming the objectionsto the abovespecified form of machine.

In carrying out my invention I provide two cylinders, about which Icause the long warp or strand of warps to travel, on the principle of ahelix or corkscrew, one end winding on said cylinders while the otherend unwinds therefrom, and in which currents of air or gas, hot or cold,are caused to pass through the layer or layers of warp-strands formedabout or between the cylinders, whereby the said drying air or gas inpassing in contact with the travelingwarp carries off the moisture. Thisoperation may take place within a close chamber, if desired. In thismanner the wet yarn passes into the chamber at one place and emerges atanother, but not until it has passed back and forth within said chambera large number of times, so as to form one or more layers of warpthreads or strands through which the hot or cold drying air or gases isforced or drawn.

I provide suitable means for the proper manipulation of the warp instarting up the machine, as will be found fully described hereinafter.

I would here remark thatI do not limit myself to any specific details ofconstruction of the machine for carrying out my invention, though Idescribe a preferred form.

In the drawings, Figure 1 isasectionalelevation of my improveddrying-machine on line as x of Fig. 2. Fig. 2 is, a sectional plan viewof Fig. 1 on line 3/ y. Fig. 3 is a sectional elevation of amodification of my ma- .chine, showing-duplication of parts, and alsothe heater for the drying medium. Fig. 4 is a perspective view of oneofthe comb-guides;

.and Fig. 5 is a perspective view of cylinders,

chains, and traveling supporting guides or bars.

A is the drying-chamber.

B are inlets at the top, and C are suctionfans at the bottom for keepingup a current of dry air or gas, which maybe cold or heated, as indicatedin Fig. 3, in which S is the heater, and BY is a pipe or flue forleading the hot airor gas to the inlets B.

It is evident that, if desired, a pressureblower might be used in placeof the exhaustfans, as these are equivalents in practice.

Preferably within the chamberA and at its sides are arranged twocylinders or shafts D E, between which the air-currents are caused topass. These two cylinders or shafts are mechanically connected together,preferably as shownthat is to say, bya chain F,whereby both shafts orcylinders are caused to rotate at equal surface speeds. The shaft orcylinder E is driven by gears O and belt-pulleys P or otherwise, asdesired. The front end of the chamber A is formed with a transverse slot1), through which the warp or strands pass to the cylinders.

II is a transversely-moving belt arranged below the opening 6 and guidedabout the Wheels I I, the former of which is driven from shaft m by aclutch device M. The shaft m is driven from cylinder D by gears N. Theclutch is operated by levers L K and rod 7a. The belt His provided witha yarn-guide h and a-projection J, which latter (when the guide hreaches the distant end of the cylinder D) strikes the lever K andthrows out the clutch, arresting further movement of the belt H.

The belt or chain F may be provided with a clamp f or any suitableholder or catch upon which the end of the Warp may be tem porarilysecured when starting up the ma chine to form the layers of warp, asshown in Fig. 3,in which the formation of such layers is in progress.-The guide It insures the warp passing onto the cylinders in a gradualand uniform manner and equally separated from adjacent warps or parts ofthe same warp. It is evident that two or more warp-strands may be run inat the same time parallel to each other without anymaterial modificationof the apparatus. If the cylinders D and E are separated a considerabledistance the warp-strands might tend to sag, and to avoid undue'tensiontransverse rods or supports of wire T may be employed. These rods T maybe stationary, as shown in Figs. 1 and 2, or they may be secured to twochains or belts F F and carried around with the warp, as indicated inFig. 5. This latter construction would in a largedegree removethe'friction of the warp on the guides T, which is of course desirable.When the .warp traverses the chamber and is wound upon the cylinders,its two ends will be located at opposite ends of the cylinders. Theinlet and outlet for the warp are thus located at relatively oppositeends of the cylinders. When the machine is full, the travel of guide hwill have ceased and the end of the warp or strand is taken out of theclampf, and as the cylinders continue to rotate the warp or strandenters through the slot 1), and after passing back and forth through thechamber, forming two parallel layers, it may emerge from aperture R ormay betaken out from the slot 1), if desired. It will thus be seen thatas fast as one end of the warp-strand Q enters the chamber the other endleaves it, and fifty to a hundred yards long may be exposed at one timeto the currents of dry air or gas passing through the said layers ofwarp so formed. As the strand of warp-threads traverses the chamberaround the guide-cylinders it is constantly presenting different threadsand giving all of the threads the same opportunity to be treated withthe drying medium. The passing air or gas, hot or cold, absorbs themoisture from the warp and dries it thoroughly before it leaves thechamber. The cylinders D E may be grooved, if desired, as indicated at(l, to insure the proper running of the warp.

U are movable combguides, which are preferably hinged to the chamber atu and are formed with teeth W, which when lowered enter between thestrands passing around the cylinders D and E and act as positive guides.They will only be used after the cylinders have been filled. One ofthese guides is shown in perspective in Fig. 4, and the guides are shownas thrown out of position in Fig. 1. WVhen the end of a strand Q isreached, in place of running it through and then again filling themachine with a new one, the beginning of the new one is tied to the endof the previous one, and the machine is thus made to act continuously.

In Fig. 3 a number of the guide-cylinders D E are shown in the samechamber. Otherwise it is the same as above described.

By this apparatus it is evident that a most thorough drying can beaccomplished without excessively heating the room in which the operatorswork, and as the air can be changed most rapidly a quick drying is theresult. The apparatus is cheap to construct, easy to operate and keep inorder, and requires but small space for the work which it accomplishes.

While I have described this invention with particular reference todrying of warp-strands, yet it is evident that I do not limit myselfthereto, as it may be applied to ribbons or any long strands, such ascord, ropes, &c. Itis self evident that the strands might run up anddown with horizontal air-currents, if desired," as such change would besimply equivalent to turning the apparatus on end.

Having now described my invention, What I claim as new, and desire tosecure by Letters Patent, is
